SPECIFICATION forming part of Letters Patent No. 550,890, dated December 3, 1895.

Application med June 17,1895. Serial No. 558,088. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV KI'iHN, a sub ject of the King of Wiirtemberg, residing at Gmiind, Kingdom of Wiirtemberg, Germany, have invented a certain new and useful Spur with Spring-Holding Device, of which the following is a specification.

- The removable spurs hitherto known have the drawback that they are too complicated in construction and consequently are too costly, so that in practical use they have found little or no success. A great want is still felt for spurs of simple construction, easily affixed, and equally easily detachable from the heel. This requirement is supplied by the spur-adj ustment which I have invented and which is constructed on the most simple method possible and in such a manner that it can be fixed in place without any special apparatus and without any great exertion. For this purpose slots in the sides of the arms of the spur are brought into connection with catches forming part of a spring-holder placed in the heel of the boot in such a manner that the spur when in use presses firmly against the end part of the heel.

The accompanying drawings show my improved arrangement as follows:

Figure 1 illustrates a view from below of a heel with the spur in position. Fig. 2 is a side elevation of the same. Fig. 3 shows a plan after the removal of the heel-plate, the projecting plate, and the spur itself. Fig. 4 shows a section on the lines 0c :r of Fig. 1 after removal of the spur. Fig. 5 shows a view from behind; and Fig. 6 shows the method of securing the spur, while Figs. 7 to 10 show details of the mechanism.

The heel consists of two parts a 19 secured together, of which the upper part, a, serves for the reception of the locking apparatus for the spur c and is provided with a rim a, which prevents any movement of the spur in an upward direction, while the end part bears behind a projection (1, which prevents any movement of the spur downward.

The locking device, which is clearly shown in Fig. 4, is located in an aperture formed in the upper part a, and consists, essentially, of a rectangular box c, Fig. 7, in which the barf, provided with projections f, is placed. The latter is normally pressed forward by means of a spring g, Fig. 3, and is provided with two points f, with which the arms of the spur engage. For this purpose the said points f are formed somewhat hook-shaped, as shown in Figs. 3 and 9, While the arms of the spur possess recessed grooves 0, Figs. 10 to 10.

' In order to prevent dust or dirt from entering the box 6, the same is protected and inclosed by means of a shutter 71 Figs. 4 and S. In order to secure a correct adjustment of the latter upon the box 6, the same is provided with guides e, which engage in the grooves 77. of the shutter.

The above-described parts having been secured into the heel of the boot in the proper manner, the barf is pressed against the box to the right by means of the spring g, Fig. 3.

NVhen it is required to affix the spur, this is effected in the manner specially shown in Fig. 6that is to say, the points f are pushed into the recesses c of the arms of the spur, after which the spur is turned upward and at the same time pressed to the left, Fig. 6, and drawn forward, so that it comes to rest above the projection (Z. This having been accomplished, the spur is drawn to the right by means of the pressure of the spring and consequently is pressed firmly against the hind part of the heel, whereby the slipping or work ing loose of the same is entirely prevented. Itwould be clearfrom the above that the insertion of the spur can be accomplished easily and simply, while the removal thereof can take place equally easily.

The spur of my invention has the great advantage that while being so easily adjusted to the heel it can, in consequence of its simplicity, be quite as cheaply manufactured as the spurs commonly in use.

WVhat I claim is- 1. In combination, the heel having the spring bar extending transversely thereof and having the projections f at the opposite sides of the heel and the spur having arms embracin g the heel with the ends adapted to said projections and means for holding the spur at the rear of the heel against vertical displacement, substantially as described.

2. In combination, the heel, the bar extending laterally thereof having the projections f at opposite sides of the heel the spur having the arms embracing the heel with ends provided with notches c and the projection. d the central portion of the spur, substantially at the rear of the heel, substantially as deas described. 10 scribed. In Witness whereof I have hereunto set my 3. In combination, the heel having the prohand in presence of two Witnesses. 5 jections at opposite sides thereof, the spur GUSTAV KUI-IN.
